Snava, Ihagmann, Have you checked how firmly is the power cable attached to the monitor? Can you reproduce the problem by moving either end or twisting the cable in different parts? Have you tried a different power cable?

I switch on my PC, ensuring that all cables, leads
and power supplies are connected properly. The tower powers up no
problems at all. I switch the screen on, the green led lights up, the
screen is completely black. A blue box appears centrally on the screen
with the text 'power saving mode'. The green led light turns amber and
then the screen just goes black.
Please don't suggest going to control panel, as I can't get that far.
shaylane_195, Good description of problem! But you left out one or two key things to tell me. Age of monitor? Approximate total "ON" hours of use? Is unit covered by LG (Lucky Goldstar) warranty? You and only you can tell me if the screen is really BLANK, or is it only BLACK? Do flashlight test to determine true state of screen! Can you see very, very faint image of WIN-desktop holding bright flashlight near your black screen? This monitor works!!! You just need to fix the possible (1) "cold, frosty looking, thermally intermittant solder connection on the "internal switch-mode-power-supply/CCFL inverter board. Yes, your monitor along with many other CCFL back-lit LCD units of all brands also could have some BAD, swollen, leaky electrolytic filter capacitors installed on the SMPS/CCFL inverter board which will need to be replaced with new ones of higher quality. Get back to me, lmistyrel on aim. or do additional comment on fixya, after you do some reading in my and other fixya tech's profiles to discover all options you as consumer/user have open to you. Bye for now. 12fixlouie
mrmadgbull, How long will e17tg display the WIN-desktop before it goes to BLACK screen? Is it 1, 2 ...4, 5.....20 seconds? How old is unit? Does unit have internal ac to dc SMPS or external (lay on floor) SMPS? Did problem occur suddenly? What do you see on screen after "it" goes black and you shine a bright flashlight 1 inch from screen? Can you still see some icons being faintly displayed?? Is unit out of it's warranty period? If lcd panel is both black and blank, "switch-mode-power-supply" could be in full shutdown mode. If you see desktop, SMPS is in partial shutdown mode. You or electronics technician will need to evaluate and repair unit. Read my FIXYA profile for more options you may have open to you. Your monitor no different than any other "cold-cathode-fluorescent-lamp" backlit LCD monitor. There is a lot of DIY videos on YOUTUBE that deal with this type of monitor problem. Lots of tech types pick-up "black screen" lcd monitors at resale shops and refurbish them for less than $20 total cost, and they will work for another 2 -4 years. Do your research before making hasty decisions. If pocket is deep with disposable income, then just use e17tg as trade-in for new wide screen. Hope this was of some help. 12fixlouie
Disconnect the monitor signal cable from PC and switch on your monitor. It should show some logo with Red, Green and Blue colors with a message similar to "No signal". If so, your monitor is working fine. Sometimes if the brightness and contrast is set to zero using controls present in the monitor, it will not show up anything. check wheather somebody set your monitor brightness and contrast to zero. If so incease them. As a last try connect to different PC and check before approaching a service center. I hope this will help you out. :)
joel_herrera, Yes, this is a very common symptom of a failing Switch-Mode-Power-Supply and/or Inverter circuit! Very common in 2-4 year old lcd/fpd's. How old is your's? Do you have warranty? Have you tried the Flashlight test? DO THIS! Reconnect lcd monitor to your fully booted PC with a known good WIN desktop screen. Then power "on" the HD2201 and tell me what happens and what you see or don't see after the screen goes BLACK! Shine a bright flashlight onto the screen at different angles and let me know the results. I'm louie12fix on fixya or lmistyrel @aol.com BYE
"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.
Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.
